I definitely built the best Gmail alternative on Cloudflare - Just added MCP and Assistant Agent Setup unlimited custom domain email here: 👉

Mailflare is free to use an open-source But if you'd like to support, grab a Pro license for $19 today ($29 from tomorrow)

@Cloudflare Just wondering if I send email with this, will the recipient see the from email of my custom domain? Or the random one from Cloudflare?

@Cloudflare They'll see from your domain

@Cloudflare Wow 🤩 that means I could replace that with my Google business email?

@Cloudflare Yes, but you do need to subscribe to Cloudflare Paid Worker $5/m But you'll have unlimited email address, Gmail still have the best deliverable though

@Cloudflare That looks so good, man

@Cloudflare Thanks to whoever designed gmail 😆

these always make me laugh. brother, you're polling way too much. why are you polling even when nothing changes? ideally you should check for idle stream with rows_read at least, and compute email state once per poll then reuse it. you're gonna wreck peoples worker usage with this, especially factoring in other emails, domains and regular account usage elsewhere.

@Cloudflare Happy to accept a PR, always room for improvements

@Cloudflare just feed my comment to your agent, i'm sure it will figure it out.

@Cloudflare love that the inbox has an MCP agent now 👀

@Cloudflare I forked this a while back, added my own teams mode, mcp and all that. You gave everyone a solid base to work with. Integrated AgentMail protocols into it too. thing is goated.

@Cloudflare I need to work out how to set this up

@Cloudflare having unlimited custom domain email is a major plus for branding and flexibility

@Cloudflare How are you handling send approvals for the assistant? A preview of the exact recipients and message before sending would make the MCP workflow much easier to trust.

@Cloudflare Unlimited custom domains on Cloudflare was already a great combo — but MCP on top means an agent can actually work the inbox, not just receive mail. Nice build!

@Cloudflare I dont want to manage D1 and R2 for my mail.

@Cloudflare Can you add IMAP/SMTP for my parents?

@Cloudflare Sorry can't support IMAP/SMTP yet, will look into it sometime soon If possible, there are some email app that support JMAP, it'll work with Mailflare

@Cloudflare Hi, would that be possible to use 2 domain at a time with pro subscription? Also, can I ask some questions via DM before continue?

@Cloudflare i’d be curious if it will land on spam?

@Cloudflare Add a favicon to the site. Polish makes a difference.

@Cloudflare That's awesome! What a huge accomplishment. Congratulations on all your hard work paying off.

@Cloudflare Thank you!
